7-OH-DPAT stimulates cell proliferation in the ipsilateral SNC. A, B, Representative fluorescent photomicrographs depicting BrdU immunolabeling in a coronal section through the ipsilateral SN in animals treated with saline (A) or 7-OH-DPAT (B) for 2 weeks. C, Quantitative analysis of BrdU-positive cells in the ipsilateral SNC. Each bar represents the mean (±SEM, n = 6) number of BrdU-positive cells counted in the ipsilateral SNC after 2, 4, or 8 weeks of treatment. Significant difference from saline-treated controls, ∗∗p < 0.001.
